Chemotherapy is the treatment of cancer with drugs that can destroy cancer cells. These drugs are often called "anticancer" drugs. Chemotherapy fights cancer by stopping cancer cells from growing and multiplying. Anticancer drugs will sometimes affect normal healthy cells, this can cause negative side effects such as nausea and hair loss. Often times a combination of anticancer drugs may be given at one treatment and/or chemotherapy may be combined with radiation therapy or surgery.
